The phrase "a particular ratio" is correct and usable in written English.
It can be used when specifying or discussing a specific ratio in mathematical, scientific, or statistical contexts.
Example: "In this experiment, we need to maintain a particular ratio of water to solute to ensure accurate results."
Alternatives: "a specific ratio" or "a defined ratio".

An early mechanical design involved a student holding two pulleys that were moved up and down in a particular ratio.
Finally, "solid objects" that make use of vertical lines and shading should be used for comparison meters that compare two values and keep them in a particular ratio.
That occurred when the increase in temperature as function of time at the inlet of each bed follows a particular ratio.
This so-called chitin-protein complex has a particular ratio of carbon, nitrogen, and oxygen atoms bound together in chemically distinct ways, says George Cody, an organic geochemist at the Carnegie Institution for Science in Washington, D.C.
At a particular ratio of long to short alkyl chain length cationic surfactants, the pores were found to be irregular and sponge-like in structure resembling that of a bicontinuous structure.
Each of the individual experimental runs at a given particular ratio and temperature was monitored and samples were collected at reaction times intervals of 1, 2, 3, 4 and 5 h for analyses.
In Table 1, Software and Hardware refer to the run time of a particular component; Ratio is the ratio of software time to hardware time, showing the speedup or slowdown of the hardware program.
Hence, from the mentioned observations, it is clear that the optimum control in peak acceleration for a particular frequency ratio is obtained with higher water depth ratios, and maximum reduction in response is obtained when the frequency ratio becomes unity.
With the help of the mentioned observations, it is clear that the optimum control of peak responses for a particular frequency ratio is obtained with higher values of mass ratios.
The material behaviour is assumed to be plane stress orthotropic for a particular load ratio, while the elastic properties can vary with the load ratio in order to represent the complex interaction between warp and fill yarns.
